What is Epclusa and what is it used to treat?
Epclusa is a brand of hepatitis C treatment that combines sofosbuvir and velpatasvir. It is used to treat chronic hepatitis C infection in adults, and in some cases in pediatric patients, depending on the indication.
What’s in Epclusa (and how do sofosbuvir and velpatasvir work)?
Epclusa contains two direct-acting antivirals:
- Sofosbuvir targets the hepatitis C virus RNA replication step.
- Velpatasvir targets the hepatitis C virus NS5A protein, which helps the virus replicate and assemble.
Used together, the combination works to stop hepatitis C from multiplying and to clear the virus in many patients.
Who can take Epclusa, and are there key before-treatment checks?
Eligibility depends on factors such as hepatitis C genotype, prior treatment history, and the presence of cirrhosis (including compensated vs. decompensated disease). Clinicians also check for:
- Existing liver function and cirrhosis status
- Co-infection with HIV or hepatitis B virus
- Current medications, because drug-drug interactions can be important with hepatitis C regimens
What drug interactions matter most with Epclusa?
Drug interactions are a common concern with direct-acting antivirals. The most important interactions typically come from:
- Strong inducers of certain liver enzymes/transporters, which can reduce Epclusa levels and lower effectiveness.
- Other medicines that affect similar pathways.
Because interaction risk depends on the exact drugs and dosages, a prescriber/pharmacist typically cross-checks the patient’s full medication list before starting.
How long is Epclusa taken?
Treatment duration depends on the patient’s hepatitis C characteristics (for example, cirrhosis status and whether the patient has been treated before). The prescribing information defines durations by regimen type and population.
What happens after treatment: cure, relapse, and follow-up testing
Patients are typically monitored with viral load testing during and after the course of therapy to confirm the virus is no longer detectable. Follow-up also matters for people with cirrhosis because even after cure, liver monitoring may still be needed.
What does Epclusa cost, and is there a generic/biosimilar option?
